Bob,

Measurement problems like this are not relegated only to the olden days.
Remember when Paddy tried to land something on Mars a few years ago?  Mixing
meters and feet, even in the NASA, era is not a good idea.  (Paddy: I apologize
if it wasn't your fault.)  :-)

 observe the differences in measurements or disregarding 
 them is an indicator, perhaps the designers,
 engineers and craftsmen 
 were not as good as
 they might have been or succumbed to other pressures 
 than their own talents."
